Welcome New Grad Students, Fall 2014!

Marisa Acosta graduated with her B.S. in Geology from Western Washington University in the summer of 2014. While at Western, she studied igneous and metamorphic petrology. At the University of Oregon, she will study experimental petrology with James Watkins. Aside from rocks, her interests include earthworms and bird-watching.  Acosta
Giselle Conde earned a dual B.S. in Geology and Spanish from the University of Wisconsin-Eau Claire. She began collaborative research as a freshman, conducting geochemical and micro-FTIR analyses on a collection of obsidians from the Near East. Since then, she has expanded her research to study the geochemical effects of hydration during the transition from obsidian to perlite. She has conducted field work in Colorado, Montana, and Argentina and presented her research at several national and international conferences. After graduating, she was awarded a year-long Fulbright grant to study geology in Reykjavik, Iceland. A native ‘Sconnie, Giselle loves cheese, her two adorable Aussies, bluegrass, and wild places. She is very excited to move to Eugene and eager to begin work with Jim Watkins researching bubble geobarometry in obsidians. ???????????????????????????????
Brennan O’Connell graduated from Colorado College in 2013 with a degree in Geology. After a variety of field oriented projects both for an undergraduate thesis in sedimentary geochemistry as well as a field mapping project with AngloGold Ashanti, she decided to pursue her interests in sedimentology, tectonics, and geochemistry with Becky Dorsey. While she wasn’t working on geology as an undergrad, she played on the CC women’s soccer team. Now she enjoys all sorts of outdoor adventures, is training to become a competitive Olympic weightlifter, and has a fondness for turtles. Brennan picture
Dan O’Hara graduated from the Indiana University of Pennsylvania with duel B.S. degrees in Geology and Applied Computer Science and a minor in Mathematics. As an undergraduate, Dan has worked on multiple research projects, completing summer internships at the Virginia Institute of Marine Science (VA); the Institute of Mine Mapping, Archival Procedures, and Safety (IMAPS) (PA); and Academia Sinica (Taiwan). His major research project as an undergraduate involved understanding deformation in eastern Taiwan, an area of active arc-continent collision, using earthquake focal mechanism solutions. OHara_Pic
Daniel Sulak is originally from Colorado. He received a B.S. in Global Environmental Science from the University of Hawai῾i where he participated in sediment geochemistry research and published a paper with Kathleen Ruttenburg. He has since been working primarily in fisheries management in the mountains of Colorado and Washington State. Dan enjoys spending his free time outdoors skiing, kayaking, biking, or running. Dan plans to pursue a Master’s degree in physical oceanography with Dave Sutherland. sulak uo bio
David Zakharov was born and grew up in Moscow, Russia where he completed his degree in mineralogy, petrology and applied geochemistry (almost equivalent to master’s degree) at the Russian State Geological Prospecting University. His research interests are focused on Precambrian magmatism, alkaline igneous systems and granite petrology. David worked on different aspects of igneous processes at several institutions: Vernadsky Institute, Russia; Geological Institute, Russia; University of Illinois; University of Manitoba.  He came to the UO to work with Ilya Bindeman on the early Proterozoic magmatism and its relation to the first glaciations.  When not busy with his studies, David enjoys trying to make his interest visible for everyone via his blog (  In addition to that, he likes to play and listen to music, learning new words in English and watching Greco-Roman wrestling.
